Depending on the production standards your sensor
conforms with, none of the diagrams displayed below
may correspond to the colors of you sensor’s wire. In
such cases, please refer to the manufacturer’s data
sheet.
The spring-loaded terminals of older models were
replaced with screw terminals in version 1.1.

You will require the following tools, in order to connect a
sensor.
A tool with a fine tip, e.g. a fine screwdriver or a pair

Two DIP switches located above the terminals for the
cable cores are used to select whether the sensor is
connected to Querx PT using two, three or four cable
cores.
